| English abstract | The effect of seven natural diets on the development and reproduction of Bonagota cranaodes (Meyrick) was evaluated under laboratory conditions. The experiments were carried out at the temperature of 23 ± 1ºC, with 70 ± 10% of RH and a photoperiod of 16:8h (L:D). The larvae were reared on apple, grapevine and honeysuckle (Lonicera japonica). On the first two foods three types of diet were used: spring leaves, summer leaves and fruits. The number of instars varied from five to seven. The larvae reared on apple leaves had, in general, fewer instars than those reared on grapevine and honeysuckle leaves. The duration of larval development differed between diets. The larvae reared on spring apple leaves showed the shortest duration, and those on fruit the longest. The larvae survival was lower on fruit than on leaves, and on apples it was particularly low (17.8%). The female pupae reared on honeysuckle were heavier than those reared on the other diets. The cycle from the egg to the emergence of adults varied between 41 days on spring apple leaves and 60 days on apples. The females reared on honeysuckle and spring apple leaves were the most fecund, whereas the females on apples did not oviposit. Honeysuckle and spring leaves were the most suitable foods. Apples, on the other hand, were the least suitable diet, which leads one to think that larvae could hardly complete their whole cycle on this fruit |
| Portuguese abstract | Foi avaliado, em laboratório, o efeito de sete dietas naturais sobre o desenvolvimento e a reprodução de Bonagota cranaodes (Meyrick). Os experimentos foram conduzidos a 23 ±1ºC de temperatura, 70 ± 10% de UR e fotoperíodo de 16:8h (L:E). As larvas foram criadas em macieira, videira e madresilva (Lonicera japonica). Para os dois primeiros alimentos foram utilizados três tipos de dietas: folhas de primavera, folhas de verão e frutos. O número de ínstares larvais variou entre cinco e sete. As larvas criadas em folhas de macieira apresentaram, de modo geral, menor número de ínstares, quando comparadas com aquelas criadas em folhas de videira e madresilva. A duração do desenvolvimento larval diferiu entre dietas. As larvas criadas em folhas de macieira-primavera apresentaram a menor duração e as criadas em frutos a maior duração. A sobrevivência de larvas foi menor em frutos que em folhas, principalmente em maçã (17,8%). As pupas fêmeas criadas em madresilva foram mais pesadas que as criadas nas demais dietas. O ciclo de ovo a emergência de adultos variou entre 41 dias em folhas de macieira-primavera e 60 dias em maçã. As fêmeas criadas em madresilva e folhas de macieira-primavera foram as mais fecundas, sendo que aquelas provenientes de maçã não ovipositaram. Madresilva e folhas de primavera foram os alimentos mais adequados; em contraposição, as maçãs foram a dieta menos adequada, o que sugere que dificilmente as larvas possam completar o ciclo sobre esse alimento |
